Acid Rain

Acid rain is rain that is polluted. The pollutants go up to the atmosphere and when it rains, it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain, snow, hail, or even fog. The scientific term for acid rain is acid deposition which means when the acid is taken from the air and is deposited on the earth. Major industries, coal burning factories, power plants and automobile engines are the main sources of sulfur dioxide and nitrogen oxide which cause acid rain. Volcanoes and forest fires also causes sulfur dioxide and nitrogen oxide.

Some of the many problems that come from acid rain is the killing of many plants and underwater life in thousands of lakes and streams around the world. It strips forest soils of nutrients and damages farm crops. Acid rain can also corrode stone buildings, bridges, and priceless monuments. Acid rain can also be harmful to humans because acid rain kills the crops and fish we eat, ruins homes, and the acid can release lead in the pipes and the lead could go into our drinking water. It is hard to determine where acid rain may fall next, because the wind from a polluted area could carry pollution


Some plants need and require soil, and the farmers do not want lime to be put in there soil. If acid requiring plants, such as some types of shrubs, are put in alkaline soil those plants are very likely to start to look yellow and very sickly very soon. Even if the water you give to the plants came from limestone strata it could neutralize the soil. Continued use of some types of fertilizer may be cause the loss of acidity, too. If the soil does not have enough acid in it, it may be made more acidic by the application of alum, sulfur, or by adding gypsum to the soil. To add more acid to the soil you can also lift the plants and replacing the whole bed to a depth of nine inches with acid soil. It is not easy to make neutral soils acid. Sulfur is the most commonly used to increase the soils acidity, but it acts very slowly. So acid rain is good for some plants in some places with alkaline soil because some of the plants want acid. Some acid requiring plants are several popular shrubs, including azalea, camellia, gardenias, blueberries, and rhododendron. Soils can be acid, alkaline, or neutral. The amounts of alkaline and acid in the soil influence the biological and chemical processes that take place in the soil. Highly alkaline or acid soils can harm many plants. Neutral soils can support most of the processes.

Soil is formed when rocks are broken up by the weather and erosion and mixed with organic matter from plants and animals. The term soil generally refers to the loose surface of the Earth, made from solid rock. To the farmer, soil is the natural medium for growth of all land plants. The rocks that make up soil could be acid, neutral, or alkaline, another name for a base. Limestone and chalk are rocks that are formed from tiny shells that are rich in calcium. Alkaline is made up of calcium. When acid rain falls on alkaline soil the calcium makes the acid become weaker or neutralize. Farmers put lime (a very strong alkaline substance) and special fertilizers in there soil naturalize the acid in the soil on a regular daily basis.
